LX2160A - Does it support ARM v8 cryptography extensions?

nb1 — Tue, 27 Apr 2021 12:16:12 GMT

Hi,

Does the LX2160A support ARM v8 cryptography extensions? (Both AES and SHA1/256)

Support in A72 cores is optional as far as I understand, hence the question. I couldn't find any reference to this in the LX2160A documents unfortunately.

Thanks!

The optional Cortex-A72 processor Cryptography engine supports the ARMv8 Cryptography Extensions ( including AES and SHA1/256, please see https://developer.arm.com/documentation/100097/0002/introduction/about-the-cortex-a72-processor-cryptography-engine ) The QorIQ LX2160A Reference Manual available on the LX2160A nxp web page on page 223 (Rev. 0) says “Included Armv8 cryptography engine.”

Perfect, thank you very much, I had missed that in the manual
